Deck latch assembly for a scaffold platform

A side rail assembly for a scaffold, comprising:

• a side rail configured to be supported between two ladder frames in first and second orientations, the side rail comprising:
• first and second support surfaces for supporting a deck of the scaffold in the first and second orientations respectively;
• the first and second support surfaces disposed on opposing sides of a horizontal plane;
• upper and lower outer sections disposed generally parallel to and farther from the horizontal plane than the first and second support surfaces;
• first and second slots disposed in the upper and lower outer sections, respectively;
• wherein the first and second slots are vertically aligned;
• a twist latch assembly comprising a shaft, a collar slidable along the shaft, a locking tab, and a compressible bias element to bias the locking tab into engagement with the deck and secure the deck against one of the support surfaces of the side rail depending on the orientation of the side rail assembly;
• wherein the twist latch assembly is configured to be removably engaged with the first and second slots of the side rail in both the first and second orientations;
• wherein the shaft comprises a reduced size section in an upper end portion proximate the locking tab;
• wherein the collar is slidable between a normal position closer to the locking tab and a retracted position farther from the locking tab;
• wherein the collar covers the reduced size section when the collar is in the normal position;
• wherein the collar is positioned to expose the reduced size section in the retracted position;
• and
• wherein the twist latch assembly is configured so that the collar is disposed between the bias element and the first slot when the locking tab is engaged with the deck and the deck is resting on the first support surface.

A scaffold comprising:

• first and second ladder frames;
• an adjustable height platform configured to be supported between the first and second ladder frames at a user selected height in an adjustment range, the adjustable height platform comprising:
• a pair of spaced-apart side rail assemblies extending between the ladder frames;
• each side rail assembly comprising a side rail;
• a deck supported on opposing sides by the side rails, the deck including at least one recess in a top surface of the deck adjacent one of the edges of the deck;
• at least one twist latch assembly removably mounted to each side rail, each twist latch assembly comprising:
• a locking tab configured for engagement with the recess in the top surface of the deck to secure the deck on the side rails;
• a shaft having a reduced size section in an upper portion proximate the locking tab;
• a bias element configured to bias the locking tab into engagement with a corresponding recess of the at least one recess;
• a collar slidable on the shaft and disposed between the bias element and the locking tab;
• wherein the collar is slidable along the shaft to selectively cover and expose the reduced size section;
• wherein each twist latch assembly extends through corresponding slots in a corresponding side rail and is rotatable between:
• a disengaged position where the locking tab does not overlap the deck allowing the deck to be installed or removed from the side rails;
• and
• an engaged position in which the locking tab extends over the top surface of the deck and engages with a respective one of the at least one recess in the deck so that the locking tab is flush with or below the top surface of the deck.
